介绍了伴随铝合金M IG焊过程中产生的氧化铝烟尘对焊接操作者的危害和影响。铝合金烟尘可引发多种慢性疾病,但由于潜伏期长,危害性不易引起人们的注意。铝合金焊接过程中产生的氧化铝烟尘具有悬浮时间长的特点,普通防护面罩难以实现良好的防护效果。提出了具体的防护措施,并指出铝合金M IG焊过程中的铝尘防护必须引起高度重视。
Describes the hazards and effects of alumina soot produced during MIG welding of aluminum alloy to welding operators. Aluminum dust can cause a variety of chronic diseases, but due to the long incubation period, the harm is not easy to attract people’s attention. Alumina soot generated during the welding of aluminum alloy has the characteristics of long suspension time, and the common protective mask is difficult to achieve good protective effect. Put forward specific protective measures, and pointed out that aluminum alloy M IG welding process aluminum dust protection must pay close attention.
